Specifications

Product Data

• Applications: ELISA, ID, IF, IP, WB
• Recommended Dilution: Can be used as unlabelled secondary antibody for Indirect detection of IgE in Human cell, tissue substrates and body fluids in immunofluorescence and immunoenzyme assay methods; for the production of immunoconjugates with a selected marker; to prepare insoluble immunoaffinity adsorbents by coupling to an artificial carrier; as catching or detecting antibody reagent in non-isotopic assay methodology (e.g. ELISA) to identify and measure IgE in human serum or other body fluid. When applied in any immunocytochemical or histochemical staining procedure or solid phase coupling technique, the optimum concentration of the IgG preparation should be established.
  Recommended Working Dilutions:
  Histochemical and Cytochemical Use: 1/100-1/250.
  ELISA and comparable non-precipitating antibody-binding assays: 1/500-1/5,000.
  Performance testing: Isotype specificity and quantitative specific recognition ability are further evaluated at the high level of sensitivity by direct singe and simultaneous double staining of different types of human cells, using counterstaining with reference conjugates with a different marker. The immunoconjugate is further tested in ELISA-type assays.
• Reactivities: Human
• Host: Goat
• Isotype: IgG
• Clonality: Polyclonal
• Immunogen: Purified homogenous IgE isolated from Human serum.
  Freund’s complete adjuvant is used in the first step of the immunization procedure.
• Specificity: The reactivity of the antiserum is directed to the Fc subunits of the IgE molecule which represents strict isotype (class) specificity. In immunoelectrophoresis and double radial immunodiffusion, using various antiserum concentrations against appropriate concentrations of IgE, a single precipitin line is obtained which shows a reaction of full identity with the precipitin line obtained with the used immunogen. It does not react with human IgG, including all subclasses, IgA, IgM and IgG/Fab or any non-Ig protein in human serum.
  Cross-reactivity: Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since immunoglobulins of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail because of the low level of IgE in most species.
• Formulation: PBS, pH 7.2 without preservatives.
  State: Azide Free
  State: Lyphilized purified hyperimmune IgG fraction
• Reconstitution Method: Restore by adding 1.0 ml sterile distilled water.
• Concentration: 10.0 mg/ml
• Purification: Salt Precipitation and DEAE-Chromatography.
• Storage:

  Prior to reconstitution store at 2-8°C.
  Following reconstitution store undiluted at 2-8°C for one month
  or (in aliquots) at -20°C for longer.
  Avoid repeated freezing and thawing.

• Note: Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibody activity reacting with other components of the immunoglobulin system and to any other serum protein. Special attention is given to the elimination of antibodies to the common Fab portion of immunoglobulins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
